Application filed September 9, 1918. Serial No. 253,170.

T 0 all whom it may concern Be it known that we, EDWARD STARK and JosnrnEnrica, citizens of the United States and residents, respectively, ofCleveland. in the county of Cuyahoga and State of Ohio, and Cleveland,in the county of Cuyahoga and State of Ohio, have invented a certain newand useful Improvement in Drophcad- Sewing-Machine Cabinets, of whichthe following is a full, clear, and exact description.

This invention relates to the kind of drop head sewing machine cabinetsin which a headsupporting platform is hinged near its front edge to thetable or-top of the cabinet, and has a flap or leaf hinged to its rearedge,the said platform and flap being of such size and shape that whenthey are aligned and in the horizontal working position'theysubstantially fill a hole in the top of the cabinet.

The object of this invention is to provide simple and inexpensive meansfor compelling the said flap or leaf to become aligned with the headplatform when the latter has been swung into the horizontal workingposition. :Another object of the invention is to pro vlde the means foraccomplishing the above specified result in such form that they arewholly out of sight when the head platform and its flapare in theworking position.

The invention consists in the construction and combination of partsshown in the drawings and hereinafter described and pointed outdefinitely in the appended claims.

In the drawings, Fig. lis a plan view ofa sewingm'achine cabinet inwhich the present invention'is embodied, when the head supporting theplatform and flap are in the horizontal working position; Fig. 2 is abottom view ofa part of one side of the head supporting platform and itsflap and the ad jacent parts of the open frame which they fillwhen theyare'in the horizontal working position, in which they are shown in 45said figure; 3 is a side elevation of the rear portion of the headsupporting plat form and its flap showing in particular the means bywhich they are connected together;

Fig. 4 is a sectional side elevation showing theposition of the headsupporting platform and its flap'and the parts associated therewith whensaid platform is swung down below the table Fig. 5 is a sectionalview inthe plane of line act-era 10 represents the table of the cabinet;

12 represents an open rectangular frame securedto the top of the tablearound a suitable opening 10 therethrough, thereby becoming a part ofthe table 15 represents the head supporting platform, that is to say, itis a platform upon which the sewing machine head is to be secured; 20represents a flap which is hinged to the rear of the platform by meansto be presently described.

The platform and its flap are of such dimensions that when they are inalignment in the horizontal working position they substantially fit therectangular head opening in the frame 12. The platform adjacent itsfront edge is hinged to the frame by suitable mcans, as for example, twopintle pins 13 secured to the side members of the frame 12 project intoholes in metal bars 14: which are secured to the sides of the platformnear the front edge thereof whereby said platform may be swung up tohorizontal working position within said frame as shown in Figs 2 and 3.or down below the table, as shown in Fig. l. i

35 represents an extension top whichis hinged to the left side memberofthe frame 12 on an exis at right angles to the axis of the hinge of theplatform. This extension top may be in the position shown in Fig. 1,where it uncovers the openingthrough the frame and serves as anextension of the table 10 or it may be swung through an arc of 180 to aposition such that it will rest upon the frame and cover the openingtherethrough.

This extension top serves as a lever by means of which the platform maybe swung up to and held in the horizontal position, or may be allowed toswing down into the substantially vertical position thereby carry-- arecommon in this art. They consist of a cable 36 which is fixed at one endto the extension top at a suitable distance from the hinge axis thereof,and at its other end to an arm 16 fixed to the under side of the machineplatform and extending rearward therefrom. This cable goes through thetable 10 and runs over suitable cable guides therefon As the extensiontop is swung to the working position shown in Fig. 1 it pulls platformup into the horizontal working position, also shown in that'figure; whenthe extension top is swung over to the closed position it permits themachine platform to swing down to the position shown in Fig. 4.

In order to pivotally connect the flap 20 to the head, supportingplatform 15, two thin fiat metal bars 23 are employed. Each of these issecured in a recess below an overhanging flange 22 which is a part ofthe flap. Each of these bars extends forward into a recess 18 let intothe side edge of the head platform below a flange 19 which overhangs thesaid bar 23 and conceals it from view.

Pivot pins 31 go through holes in these bars and screw into the edges ofthe plat form, and thereby the flap is hinged to the rear edge of theplatform. The lower edge of that part of eachb ar 23 which is fixed tothe flap is formed with an integral outwardly extended flange 25, therear end 26 of which is curved downward slightly. There is also aninwardly projecting finger 27 bentinward from the lower edge 'of thatpart of each bar which extends in front of the pivot screw, andtherefore extends beneath the platform 15.

A contractible coiled spring 37 is connected at one end with therearwardly'extended stud 46 fixed to'the head platform 7 near its rearedge and at the other end to a shown in Fig. 4.

the outwardly extended flange 25, and at first, the curved front end 26thereof will engage the lower surface of an overhang ing part l2' of theframe 12, as shown in Figs. 5 and 6, and thereby the front 'end of theflap will be prevented from going up while its rear end goes up with theplatform,

and both come to the horizontal position shown 'in Fig. 3, where, asbefore stated, they substantially fill the opening through the frame 12.When they come to this p0- siti'on the said flange 25 by its engagementwith the under surface of the overhanging part l2 'of-the frame preventsany upward swing of the flap; and the finger 27 coming into contact withthe underside ofthe head platform near its rear'end will'by thisengagement limit the upward movement of the head platform.

It is apparent that the means by which the flap and the head platformare pivoted together as well as the means carried by the pivot bars 23to bring about the horizontal alignment of these two parts arecompletely hidden from view bythe overhanging flanges 19 and 22.

While it is desirable to provide these plates23 at both ends of the headplatform with the flanges 25 and finger 27 above referred to, it mightserve the purpose if only one of such bars were so provided with theseflanges; or if a bar at one end carried the flange and the bar at theother end car ried the finger.

Having described our invention, We'claim:
